            The header:

<pre class="programlisting"><span class="special">&lt;</span><span class="identifier">boost</span><span class="special">/</span><span class="identifier">regex</span><span class="special">/</span><span class="identifier">icu</span><span class="special">.</span><span class="identifier">hpp</span><span class="special">&gt;</span>

            contains the data types and algorithms necessary for working with regular
            expressions in a Unicode aware environment.
          </p>
<p>
            In order to use this header you will need the <a href="http://www.ibm.com/software/globalization/icu/" target="_top">ICU
            library</a>.
          </p>
<p>
            The header will enable you to:
          </p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
                Create regular expressions that treat Unicode strings as sequences
                of UTF-32 code points.
              </li>
<li class="listitem">
                Create regular expressions that support various Unicode data properties,
                including character classification.
              </li>
<li class="listitem">
                Transparently search Unicode strings that are encoded as either UTF-8,
                UTF-16 or UTF-32.
              </li>
</ul></div>
<p>
            CMake users should link to the <code class="computeroutput"><span class="identifier">Boost</span><span class="special">::</span><span class="identifier">regex_icu</span></code>
            target in our CMakeLists.txt in order to have ICU dependencies taken
            care of when using this header.
